Buses are like HS2
The wrong solution to the wrong problem.
HS2 does not solve transport problems and is a centrally planned solution to a non existent problem. Technology has already made the issue mute. WiFi on trains, 3G/4G mobiles, charging points, all allow people to work on trains so it doesn't matter that the trip takes 30 minutes longer than a hypothetical HS2.
Buses do not solve transport problems either. Centrally planned (bus routes set by planners) with no regard to how people actually live and work. Buses cause just as many traffic problems as they solve. Rather than trying to use an inappropriate method to solve transport issues, the best thing that politicians and civil servants could have done is to have done nothing. Technology always progresses at rate to overtake centrally planned solutions which is hindered by bureaucracy and red tape.
It's not so much that Google cars are a better solution to buses, but that UberTaxi is just as good. Anything that adapts to how people really live and work is the best solution. Maybe that might mean more small apartments closer to workplaces or more renting so that the workforce is more mobile and not tied to overpriced houses or it could mean better traffic flow or something that no one has thought of yet.
